Some simple primitives for event-based discrete event simulation.

This library provides several ways of describing a finite Markov Decision Process (MDP) model (see FiniteMDP::Model) and some reasonably efficient implementations of policy iteration and value iteration to solve it (see FiniteMDP::Solver).

An OmniAuth Strategy for the figshare API. You can use it to authenticate users against the figshare API in your ruby on rails / sinatra / other rack-based web application.

Compare compression algorithms (gzip, bzip2, xz, etc.) for a sample of documents.

Includes solvers for continuous and discrete multivariate optimisation problems.

A small embedded DSL for implementing stateful protocols in EventMachine using finite state machines.

Runs a small number of setup tasks, followed by a bunch of expensive tasks in parallel. This manages the number of running tasks and keeps the visible output to a small and useful amount. It was created to make developer pre-commit builds really fast, but still able to cover a lot of tests.

Store key-value pairs in file names, e.g. parameter names and parameters.

The gem push command makes it incredibly easy to publish your gems... maybe a little too easy. PushSafety is a RubyGems plugin that refuses to push a gem unless it is on a whitelist. Add your open source gems to your whitelist, and keep your private gems safe from accidental pushes.

Store selected request parameters to cookies for use in future requests. Useful for affiliate, referral or promotion links.

Ruby interface for the RELAX IV code by D.P. Bertsekas and P. Tseng.
